Question about Spa Parts Plus GFCI, Circuit Breaker, 30 Amp

30 amp 2 pole GE GFCI breaker pops on hot tub after hrs of use

My 30 amp GE 2 pole GFCI breaker for hot tub keeps popping after hrs of use, usually overnight. Happens when heater on or off. Reading 23 amps on two hot lines. What is the limit on the neutral (volt and amps) when it should pop? I have an amp clamp and volt meter to measure. Do these breakers get weak over time and begin to pop at lower amps? The hot tub is wired correctly and is running correctly when breaker is connected, then pops after hrs of use. Any suggestions or advice on what to check? Would appreciate any advoce/help.

I have seen circuit breakers trip at a lower amperage. It seems that they are weak. Generally circuit breakers run with 80% load with no problem, in your case 24 amps. I would replace the circuit breaker.

Hello shanleys, I have had situations simular to that and have found that the breaker was bad ( weak ) a breaker in working condition should last for years if not a life time of the product, I would check that scense everything else is operating fine. The other would be too much load but it sounds like you have tested that.

My hot tub trips the GFCI. THe GFCI holds when I disconnect the wires running into the hot tub. I have disconnected EVERYTHING from the circuit board including the heater and the GFCI still trips.


Sounds like wet or bad wiring somewhere but u should do a visual inspection of all the wires & connections first then through process of elimination. Turn off breaker disconnect all wires and connect one wire then turn breaker on & if it dosent pop the. Turn it off and connect one more wire and turn the breaker on & continue until you get the breaker to pop and the last wire or board u just connected is your problem & go from there.

I just wired my hot tub into my new house. And GFCI keeps tripping?


Still would go with Miswired.
if this is an auxiliary GFCI Spa Disconnect,
240 VAC, 50 Amp, then...
All of the following needs to be this way:
  • 4 wires from MAIN Circuit panel, into GFCI disconnect box, 2 hots, 1 Neutral, 1 ground
    • 2 hots go onto the disconnects Power Bus Bar for breaker
    • 1 white Nuetral goes to Isolated nuetral bus bar
    • 1 green Ground goes to ground lug directly on the box
  • 1 GFCI in the auxiliary disconnect box
    • The White Pigtail of the GFCI Breaker goes onto the Isolated Nuetral bus bar. There are now two wires there.
  • 4 wires come into box from Spa. (Unless the spa is Specifically a 3 Wire Connection Spa!)
    • 2 Hot/Line wires will go into the L1 & L2 lugs of the breaker respectively.
    • 1 White Nuetral Wire will go into breaker as well at the "Load Nuetral lug, usually marked as 'LN'.
      • It will NOT go on the Isolated Nuetral bus bar.
    • Green Ground wire will be connected to ground lug, 2 wires are now connected there.
  • Connections at spa will be respectively connected: the 2 hots on line 1 and line 2. White wire goes to Nuetralnd green ground will go to a Ground Lug, most likely to metal control box.
If it's not wired in this manner, it is wired WRONG.

Qo260gfi not tripping


Question is not fully clear.

2-pole 240Volt gfci circuit breaker requires the white wire be connected to neutral busbar.

Easy solution for 240Volt spa that comes with gfci:
Replace spa gfci with regular non-gfci breaker.
Install 2-pole GFCI breaker in main panel, and connect wire to spa breaker.

Having 2 breakers is not a problem.
Having 2 GFCI on same circuit is a problem.

My spa depot hot tub keeps popping the breaker


http://waterheatertimer.org/Color-codewire.html
http://waterheatertimer.org/How-to-replace-circuit-breaker.html
http://waterheatertimer.org/How-to-wire-GFCI.html

What type breaker?
GFCI or ordinary heat-rated breaker?

Do NOT use two GFCIs on same circuit.
Spa needs GFCI to protect people while immersed in water.

You might have dangerous short, or leaking element, bad switch, bad wiring, bad electrical connection, or undersized wire and breaker.
If breaker is undersized for load, it can get loose on the busbar and then start arcing, and then tripping. Use nose to smell for burning. Feel breakers to see if they are warm. Move wire to different same-size breaker.

My breaker is conected to a hot tub. tub was working fine in auto mode. Turned on jets and breaker tripped. will not reset can you help me


I am assuming this is a GFCI circuit breaker? If it is it will have a "test" button on the breaker. When you say "jets" i'm assuming you mean when you turn on the blower to make the air bubbles? It could be you have a problem with the blower motor. When you start the blower, it trips the breaker. Be sure the blower is in off position when you reset the breaker. The most common fault though on a spa/hot tub is with the heater. If the element goes bad, and current flows to ground, it will trip the GFCI breaker. Again try and turn all functions off. Reset breaker, and then turn on one at a time till the breaker trips. First the pump, then the heat, then the blower.

Gfi Breaker 2 Pole 20 Amp: installed 20 amp dbl pole breaker to hot tub. Keep...


When Working with Household Electricity you want to always keep in mind that the BLACK wire ALWAYS carries DEATH. What I mean by this is that working with a Single Phase Circuit (one that uses 120VAC) the only wire that should be carrying a voltage is the BLACK one, the other 2 wires (typically the White Neutral and Green Ground) should both be electrically connected to Earth Ground (usually by being attached to your water pipe.)

It is also possible that your hot tub may use more than 20 Amps.

Hooking up a Hot tub


Everything above tells me this is 120V unit...if thats the case a single pole breaker is sufficient. Also by what you have written, a 15 amp breaker should suffice.

Gfci breaker for spa


gfci's are designed to trip if they receive voltage on there ground/neutral side, therefore my vote is for Smithbrother I would say there is probably a partial short somewhere in you system.
